Abstract

A process is disclosed for operating a fuel cell arrangement comprising fuel cells (2) arranged in a stack (1), as well as the fuel cell arrangement. A combustible gas in the first reforming units (4) in thermal contact with the fuel cells (2) is partially converted into hydrogen by an endothermic reaction, absorbing the heat from the fuel cells (2), and is supplied to the anodes of the fuel cells (2). According to the invention, more hydrogen than required in the fuel cell (2) is generated in the first reforming units (4), and part of the hydrogen-containing, reformed combustible gas is extracted from the first reforming units (4) and supplied to a second reforming unit (3), and the hydrogen contained in the supplied, reformed combustible gas is subjected in the second reforming unit (3) to an exothermic back reaction, and the thus released heat is carried away to cool the second reforming unit (3).
